Data suggest that redo mitral valve surgery is being performed in increasing numbers, possibly with superior results according to single-centre studies. The purpose of this study is to describe outcomes of redo mitral valve surgery and identify risk-adjusted predictors of poor outcomes. ⋯ Redo mitral valve surgery accounts for approximately 10% of mitral valve operations and is associated with increased risk and resource utilisation. However, as the volume of redo mitral surgery increases, outcomes have dramatically improved and are now better than predicted.

Bicuspid aortic valve (BAV) is associated with early valvular dysfunction and proximal aorta dilation with high heterogeneity. This study aimed to assess the determinants of these complications. ⋯ Normofunctional valves are more prevalent in BAV without raphe. Aortic stenosis is more frequent in BAV-RN and associated with some cardiovascular risk factors, whereas aortic regurgitation (AR) is associated with male sex and sigmoid prolapse. Although ascending aorta is the most commonly dilated segment, aortic root dilation is present in one-third of patients and associated with AR. Remarkably, BAV-RL increases the risk for dilation of the proximal aorta, whereas BAV-RN spares this area.

Meta Analysis
Implantable cardiac defibrillator and mortality in non-ischaemic cardiomyopathy: an updated meta-analysis.
The benefit of implantable cardiac defibrillator (ICD) in symptomatic patients with systolic dysfunction and non-ischaemic cardiomyopathy remains controversial. We conducted a systematic review and meta-analysis to determine the effect of ICD in patients with non-ischaemic cardiomyopathy on (1) all-cause mortality, (2) cardiovascular mortality and (3) sudden cardiac death. ⋯ Primary prevention ICD therapy reduces all-cause and cardiovascular mortality and sudden cardiac death in patients with non-ischaemic cardiomyopathy.

Multicenter Study Comparative Study
Ventricular function and vascular dimensions after Norwood and hybrid palliation of hypoplastic left heart syndrome.
Norwood and hybrid procedure are two options available for initial palliation of patients with hypoplastic left heart syndrome (HLHS). Our study aimed to assess potential differences in right ventricular (RV) function and pulmonary artery dimensions using cardiac magnetic resonance (CMR) in survivors with HLHS. ⋯ Norwood and hybrid strategy were associated with equivalent and preserved global RV pump function while development of the pulmonary arteries and reintervention rate were superior using the Norwood approach. Impaired RV myocardial deformation as a potential marker of early RV dysfunction in the hybrid group may have a negative long-term impact in this population.

Scientific knowledge on work disability in terms of sickness absence and disability pension (SA/DP) among patients with acute myocardial infarction (AMI) is scarce. The study aimed to investigate trajectories of SA/DP among individuals with or without AMI and examined the associations between sociodemographic, morbidity and coronary revascularisation characteristics with such trajectories among patients with AMI. ⋯ The majority of patients with AMI have a good outcome in terms of low levels of work disability within 2 years after AMI. Patterns of SA/DP before AMI, sex, socioeconomic status as well as comorbid musculoskeletal and mental disorders provide crucial clinical information on work disability after AMI.
